5-6) LAMP ON COLOR CHANGE BOX
Needle position lamp on the color change box blinks at the needle currently in operation. Needle set lamp on the box
blinks when the needle reaches the center of the needle hole on the plate (the roller is on the straight line movement
of the color change cam. See [Fig.5-10]). The needle moves only when the both lamps blink - which prevents
machine errors due to incorrect needle position or color change failure.
